Hello, I am trying to use an 18F2520 with a GLCD and it seems to be running really slow. The GLCD fill command takes about 5-7 seconds to finish. Here is the code that I am using with the mikroC compliler.
Doing OSCCON = 0x07 selects the internal oscillator at 32kHz. Try OSCCON = 0x72 for the internal 8MHz clock or OSCCON = 0x00 if you have an external crystal. If you have an external crystal then you may have to set the fuses appropriately.
